← Nature & AnimalsWhich outcome occurs when arid plants utilize CAM pathways?
A)Accelerated carbohydrate synthesis at night
B)Reduced photorespiration water-use efficiency
C)Stomata close during daytime✓
D)Enhanced RuBisCO access high temperature
💡 Explanation
CAM pathway plants open stomata at night to fix CO2, because crassulacean acid metabolism minimizes water loss in hot, dry climates, therefore stomata close during daytime to prevent transpiration, rather than functioning like C3 or C4 plants.
